1. The problem statement, all variables and given/known data
Hello, My thermodynamics professor gave us homework to plot 3 lines of constant temperature on a PV diagram in excel and 3 lines of constant pressure on a TV diagram.
I have no clue how to do this and was wondering if someone could help me

2. Relevant equations
He gave us the table for Ideal-gas properties of air

3. The attempt at a solution
have not attempted since I am not sure how to do it

So you have the Excel data, and just are not familiar with using the Charting Wizard?

he didnt give us any data. He just said Plot 3 constant temperature lines of your choice, e.g., T=300K on a single P-V diagram for air. In addition plot 3 constant pressure lines of your choice, e.g., P=1atm on a single T-V diagram for air.

You know what the relationship between P and V is for an ideal gas ? Can air at 300 K be considered an ideal gas ?

I am not sure what the relationship is but yes air at 300K can be considered an ideal gas
